2010-12-16n_gsm: Fix message length handling when building headerKen Mills1-2/+2
Fix message length handling when building header When the message length is greater than 127, the length field in the header is built incorrectly. According to the spec, when the length is less than 128 the length field is a single byte formatted as: bbbbbbb1. When it is greater than 127 then the field is two bytes of the format: bbbbbbb0 bbbbbbbb.

2010-12-16MIPS: LD/SD o32 macro GAS fix updateMaciej W. Rozycki2-4/+20
I am about to commit: http://sourceware.org/ml/binutils/2010-10/msg00033.html that fixes a problem with the LD/SD macro currently implemented by GAS for the o32 ABI in an inconsistent way. This is best illustrated with a simple program, which I'm copying here from the message above for easier reference: $ cat ld.s ld $5,32767($4) ld $5,32768($4) This gets assebled into the following output: $ mips-linux-as -32 -mips3 -o ld.o ld.s $ mips-linux-objdump -d ld.o ld.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <.text>: 0: dc857fff ld a1,32767(a0) 4: 3c010001 lui at,0x1 8: 00810821 addu at,a0,at c: 8c258000 lw a1,-32768(at) 10: 8c268004 lw a2,-32764(at) ... Oops! The GAS fix makes the macro behave in a consistent way and pairs of LW/SW instructions to be output as appropriate regardless of the size of the offset associated with the address used. The machine instruction is still available, but to reach it macros have to be disabled first. This has a side effect of requiring the use of a machine-addressable memory operand. As some platforms require 64-bit operations for accesses to some I/O registers LD/SD instructions are used in a couple of places in Linux regardless of the ABI selected. Here's a fix for some pieces of code affected I've been able to track down. The fix should be backwards compatible with all supported binutils releases in existence and can be used as a reference for any other places or off-tree code. The use of the "R" constraint guarantees a machine-addressable operand. Signed-off-by: Maciej W.

2010-12-16SSB: Fix nvram_get on BCM47xx platformHauke Mehrtens1-6/+11
The nvram_get function was never in the mainline kernel, it only existed in an external OpenWrt patch. Use nvram_getenv function, which is in mainline and use an include instead of an extra function declaration. et0macaddr contains the mac address in text from like 00:11:22:33:44:55. We have to parse it before adding it into macaddr. nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h through the MIPS git tree and will be available soon. It will not build now without nvram_parse_macaddr, but it hasn't before either.

2010-12-16MIPS: Fix CP0 COUNTER clockevent raceKevin Cernekee1-1/+1
Consider the following test case: write_c0_compare(read_c0_count()); Even if the counter doesn't increment during execution, this might not generate an interrupt until the counter wraps around. The CPU may perform the comparison each time CP0 COUNT increments, not when CP0 COMPARE is written. If mips_next_event() is called with a very small delta, and CP0 COUNT increments during the calculation of "cnt += delta", it is possible that CP0 COMPARE will be written with the current value of CP0 COUNT. If this is detected, the function should return -ETIME, to indicate that the interrupt might not have actually gotten scheduled.

2010-12-16PM / Runtime: Fix pm_runtime_suspended()Rafael J. Wysocki2-3/+4
There are some situations (e.g. in __pm_generic_call()), where pm_runtime_suspended() is used to decide whether or not to execute a device's (system) ->suspend() callback. The callback is not executed if pm_runtime_suspended() returns true, but it does so for devices that don't even support runtime PM, because the power.disable_depth device field is ignored by it. This leads to problems (i.e. devices are not suspened when they should), so rework pm_runtime_suspended() so that it returns false if the device's power.disable_depth field is different from zero.

2010-12-16sched: Fix the irqtime code for 32bitPeter Zijlstra1-6/+45
Since the irqtime accounting is using non-atomic u64 and can be read from remote cpus (writes are strictly cpu local, reads are not) we have to deal with observing partial updates. When we do observe partial updates the clock movement (in particular, ->clock_task movement) will go funny (in either direction), a subsequent clock update (observing the full update) will make it go funny in the oposite direction. Since we rely on these clocks to be strictly monotonic we cannot suffer backwards motion. One possible solution would be to simply ignore all backwards deltas, but that will lead to accounting artefacts, most notable: clock_task + irq_time != clock, this inaccuracy would end up in user visible stats. Therefore serialize the reads using a seqcount.

2010-12-16lguest: populate initial_page_tableRusty Russell3-5/+107
Two x86 patches broke lguest: 1) v2.6.35-492-g72d7c3b, which changed x86 to use the memblock allocator. In lguest, the host places linear page tables at the top of mem, which used to be enough to get us up to the swapper_pg_dir page tables. With the first patch, the direct mapping tables used that memory: Before: kernel direct mapping tables up to 4000000 @ 7000-1a000 After: kernel direct mapping tables up to 4000000 @ 3fed000-4000000 I initially fixed this by lying about the amount of memory we had, so the kernel wouldn't blatt the lguest boot pagetables (yuk!), but then... 2) v2.6.36-rc8-54-gb40827f, which made x86 boot use initial_page_table. This was initialized in a part of head_32.S which isn't executed by lguest; it is then copied into swapper_pg_dir. So we have to initialize it; and anyway we switch to it before we blatt the old tables, so that fixes the previous damage as well. For the moment, I cut & pasted the code into lguest's boot code, but next merge window I will merge them.

2010-12-16lguest: restore boot speedRusty Russell1-4/+7
lguest is dumb and drops *all* the pagetables for set_pte (which is only used for kernel mapping manipulation, so it's OK without highmem). But it's used a lot in boot, too. As a guest optimization, we suppressed this flushing until the first page switch. Now we have initial_page_table, that happens much earlier, so extend the heuristic to wait until we switch to something other than the swapper_pg_dir or initial_page_table. As measured on my laptop under kvm, this dropped the time-to-mount-root from 48 seconds to 4.3 seconds. Signed-off-by: Rusty Russell <[email protected]>

2010-12-16nilfs2: fix regression of garbage collection ioctlRyusuke Konishi2-9/+12
On 2.6.37-rc1, garbage collection ioctl of nilfs was broken due to the commit 263d90cefc7d82a0 ("nilfs2: remove own inode hash used for GC"), and leading to filesystem corruption. The patch doesn't queue gc-inodes for log writer if they are reused through the vfs inode cache. Here, gc-inode is the inode which buffers blocks to be relocated on GC. That patch queues gc-inodes in nilfs_init_gcinode() function, but this function is not called when they don't have I_NEW flag. Thus, some of live blocks are wrongly overrode without being moved to new logs. This resolves the problem by moving the gc-inode queueing to an outer function to ensure it's done right.
